PRESSURE GAS-VALVE AND CONTROLLING MEANS THEREFOR.

To all whom 'it may concern:

Be it known that I, FRED O. H. FINCKE, a subject of the Emperor ofGermany, and a resident of College Point, county of Queens, and State ofNew York, have invented certain new and useful Improvements in PressureGas-Valves and Controlling Means Therefor, of which the following is afull, clear, and exact, description.

This invention relates more particularly to means by which the gas to aburner or b urners may be automatically turned on or off from a distantpoint.

The primary object of the invention is to provide a simple and eflicientdevice in which a piston may be operated to control the gas to one ormore burners by means located at a distance therefrom, which means has amovable part adapted to force the piston controlling the gas-supply tothe burner in either direction to cause the light to be extinguished orthe gas to be ignited at the will of the operator, thus overcoming theobjections incident to the use of matches and other means of a similarcharacter for light-` ing the gas.

Other objects of the invention are to provide a simple andetlicientvalve casing for the burner in which the said casing may be constructedof a plurality of independent members so that the parts may be easilymade and held together and the parts of such a form that they can bereadily finished into an attract-ive and effective casing; to provide asimple and eiiicient piston for controlling the supply of gas to theburner; to provide means whereby the operating device for moving thepiston may be readily attached thereto; and to provide means which maybe applied to the ordinary type of burner or may be attached to theusual Bunsen burner.

A further object of the invention is to provide a. simple and efficientdevice for operating the gas-supply controlling piston, which isprovided with simple locking means to positively hold the piston in oneposition and which permits the piston to be automatically moved in theopposite direction to extinguish the lights.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a vertical section, partly in elevation, ofone form of device embodying my invention. F ig. 2 is an elevation ofthe burner and casing. Fig. 3 is a vertical section of the pumping oroperating device for the gas-controlling piston, the position of theparts being diiferent from that shown in Fig. 1. Fig. 4 is a sectionalplan taken on the line IV-IV of Fig. 1. Fig. 5 is an inverted plan view.Fig. 6 is a plan view of the pumping device. Fig. 7 is an enlargedvertical section of one form of casing for the gas-controlling piston.Fig. 8 is a section, taken on the line VIII*VII1 of Fig. 7. Fig. 9 is aplan view. Fig.

1() is a view similar to Fig. 7 except that the gas-controlling pistonis in a different position. Fig. 11 is a sectional plan, partly inelevation, taken on the line XI-XI of Fig. 10. Fig. 12 shows a differentform of piston and passages controlled thereby. Fig. 13 is a verticalsection of an operating device showing a different form of locking meansfor the piston thereof; and Fig. 14 is a sectional plan view taken onthe line XIV-XIV of Fig. 13.

The member 10 of the casing is cylindrical in form and is provided witha burner part 11 and a gas-supply part 12 to which the tube 13 of thegas bracket or chandelier is attached, and in the gas-supply part is apassage or port 14, while in the burner part is a passage or port 15above which is arranged the burner 16 having the usual screwthreaded endadapted to engage the threaded end of the stem or projecting part 17 ofthe casing, the said burner 16 being provided with the usual gas tip 18.The member 10 is somewhat enlarged centrally thereof, and is providedwith a transverse opening 19 therethrough in which is adapted to move apiston 2() for controlling the gas between the source of supply and theburner. This piston is provided with a transverse opening 2l and alongitudinally-extending opening 22, and said opening 21 is adapted tobe brought into alinement with the ports 14 and 15 to permit the gas topass to the burner tip, and when the controlling piston is forced to oneside as shown in Fig. 10 the gas will be entirely cut oii from theburner. The outer end of the piston opening 22 is closed by a plug orguide 23, which has one end threaded to close the end of the opening 22in the piston, and its outer end may be square or of other form and llOguided in a similarly formed opening 24 in an annular sleeve or ring 25.This sleeve or ring is held to the member 1() by a beada ing or turningover the edges thereof and extending through the sleeve member and themember 10 above the piston 20 and at an angle thereto is a needle orother valve Q6.

This valve 26 may have a threaded stem to engage a threaded opening, andits outer end is provided with a button or lingering part 27, and itsinner end is arranged to control the passage 15 to the burner so thatthe gas may be properly regulated independent of the usual gas cock. Asecond needle valve 28 extend through the sleeve or ring 25 and inadvance of the valve 28 is an opening Q9, which communicates with thesource of gas supply and with the passage 30, to which latter pilot. 31is connected, the passage of the gas to the pilot being controlled bysaid valve 28. By this means the casing and sleeve may be readily madeand held together and the parts quickly fitted so as to vmake aneifective and inexpensive valve, and at the same time provide readymeans for holding the several parts together and properly supporting thepiston for controlling the gas.

To operate the gas-controlling piston from a distant point I provide apumping or operating device 31a, which has a cylinder 32, and thiscylinder 3Q has a contracted portion 33 which is connected by a tube orpipe 34 to a nipple or coupling 35. This nipple 35 is held in a threadedopening in the sleeve 25 and communicates with the opening or chamber 19in which the controlling piston 20 moves, and said nipple has its endprovided with a packing gland 36 which is adapted to hold the tube orpipe 54 prop-A erly to said nipple. Tithin the casing 82 of the device31a is a piston 37, and this piston is cup-shaped and is normally forcedin one direction by a spring 88 arranged within the cylinder between thecontracted portion 33 and the piston 37, and projecting from one side ofthe piston 37 is a rod 39 on the outer end of which is a button orpushing device 40 whereby the rod and piston may 4be forced in onedirection against the action of the spring 38. The cylinder 32 restsupon a plate 41 through which the rod 39 passes, and around the cylinderis a threaded part or ring 42 which engages a threaded opening in a partof the casing or support 43, the latter being of wood or of any othersuitable material. This casing or part 43 is provided with a chamber orrecess 44 which is substantially wedge-shaped and inclines at the innerpart thereof to provide a pivoting point 45, at which point and betweenthe surface 46 and the plate 41 is held a locking lever 47. This lever47 has an opening through which the rod 39 passes and said opening ismade to provide a detent or engaging surface 47a to lock the rod when itis forced inward, the normal posi-V tion of the lever 47 being at anangle with' respect to the axis of said rod. The lever 47 is providedwith a stem portion 48 and the fingering portion 49, which stem portionis movable in a slot in the recessed part 44 and is normally forceddownward by means of a spring 49a having one end thereof abuttingagainst said lever and its other end fitting a recess in the casing 43.A fixed fingering or gripping device 50 having two tines or projectingparts 51 is held convenient to the gripping portion 49 of the lever 47so that the said device 50 may be readily grasped to move said lever 47to a substantially horizontal position, which will release the rod 39thus permitting the spring 38 to force the spring and rod upward, theaction of the lever 47 being substantially that of a cam toautomatically lock the rod 39 in any position it may be placed in, stillpermitting the rod to be automatically forced outwardly by the spring 88when said lever is held in a position to release the rod. Then thepumping piston 37 is forced inward by the rod 39 it will force airthrough the pipe 34 into the chamber or opening 19 of the casing 10, andwill force the piston to the position shown in Fig. 1 to permit the gasto ilow to the burner and be ignited by the pilot, but when the handle47 is moved to release the said rod the spring 38 will automaticallyforce the piston in the opposite direction and by reason of the suctioncreated thereby will force the controlling piston 2O in the oppositedirection and thereby cutoff the gas from the burner. By this means thegas may be ignited or extinguished from a distant point without the useof matches or other means for igniting the gas and without the necessityfor operating the usual gas cock.

Fig. 12 shows a slightly different form of piston and arrangement ofports for the gas in the valve casing, and particularly with respect tothe supply of gas to the pilot so that the gas to the pilot will belighted only when the gas to the burner is cut off, and the supply ofgas to the pilot cut off when the gas is burning at the burner tip, Inthis case the port 52 is opposite the port 14 as in the other figures,-and-Lafport lerpassage 53 is provided at one side which connects withthe pilot 54, the said pilot leading within the burner instead ofoutside thereof, and the gas supply thereto being controlled by a valveThe piston 56, in this case, is provided with an opening 57 whichcommunicates with the longit-udinally-extending opening 58, and thisopening connects with the transverse opening 59, the outer end of thelongitudinally-extending opening 58 being closed by the guide 60. In theposition shown the gas to the burner is cut off while the gas issupplied through the piston to the pilot. As soon as the operatingdevice shifts the piston in the opposite direction there will be nocommunication with the gas supply and the pilot passage 53, but thecommunication will be direct through the transverse opening 59 which hasbeen broughtinto alinement with the port 14; and port 52. During themovement of the piston to shut olf the gas to the burner, the same willbe ignited long enough to light the gas at the pilot so that the gas atthe burner may be automatically lighted as in the other construction,although the gas to the pilot is automatically cut olf while the burneris lighted, thus economizing in the use of the O'as.

b In Figs. 13 and l-t the pumping device is substantially the same as inthe other figures except that a different forni of locking means forholding the rod 39 is provided. As shown the part or casing 61 isprovided with a recessed portion 62 which is cut away at G3 to provide apivoting point for a lever (A having a detent or engaging part 65. Thisdetent 65 is normally held at an angle with respect to the axis of therod 39 so as to have a cam-like rocking action with respect to the sameand projecting upward from the detent are two lugs or parts 6G whichenter slots 67 in the forked end 68 of a push rod 69. This rod 69 hasits stem. 70 extending through an opening in the casing'l and aroundsaid stem is a spring 7l having one end arranged in a recess 72 and itsother end abutting against a button or fingering portion 73 carried bythe rod 69. As the rod 69 is forced inward it will force the detent 65away from the rod 39 allow ing the spring 38 to force the piston 37 andthe rod 39 downward, but when the said rod is forced inward it willraise the detent which will automatically engage said rod as soon assaid detent is released.

It will be understood that while the device is shown as controlling asingle'light it may be made to control a plurality of lights through theoperation of a single piston or a plurality of pistons as desired.

From the foregoing it will be seen that a simple and etiicient device isprovided in which the parts are cylindrical and may be readily made andassembled and the whole device made very attractive; that simple meansare provided for controlling the gas to the burner; that a simple deviceis arranged for automatically operating the controlling piston of thegas valve so as to shut ott the gas or to light the same; that simplemeans are provided for locking the piston of the pumping device to holdthe same in its proper position or to permit the piston to beautomatically forced in one direction when the locking means isreleased; and that by the means shown a Single or a plurality of burnersmay be ignited from a distant point without the'use of matches orsimilar means, and the lights may be extinguished without operating theusual gas cock.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l.
